SolidWorks has some in-built tools for generating curves from imported CAD file or data. Utilize it to create flap profiles on the airfoil. But again I am not sure about the precision of this tool.

In your situation a simple rectangular flap is assumed as a piece of cake or just an extrusion. You should ignore use of sweep for better output. By applying a nice elliptical flap curve you can place the structure using Sw design tool. Hope it helps!

Friends i done modeling. I enter the 72 co ordinate points in solid-works using point command and then draw line to join the points . Finally extruded to get blade. Thank you very much for your comments
